Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed November 5, 1907. Serial No. 400,804.

To all whom "it may concern:

Be it known that I, HIRAM RICHARD, a citizen of the United States, residing at Hooper, in the county of Costilla and State of Colorado, have invented new and useful Improvements in Presses, of which the following is a specification.

The invention relates to an improvement in presses, being particularly directed to a baling press and comprehending an improvement in the feeding mechanism and in the power mechanism for such presses.

The main object of the present invention is the provision of a power mechanism for baling presses in which a continuous even power for operating the press is supplied from the movement of the draft animals.

Another object of the present invention is the provision of feeding mechanism for the press, the parts being constructed and arranged for automatic operation so that the movement of the main or pressure piston under the influence of the power means will automatically feed the material into proper position for the action of the piston.

The invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a'plan view of my improved press. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged side elevation partly in section of the pressin apparatus. Fig. 1 is an enlar ed plan 0 the power apparatus, the dra t tongues bein omitted. Fig. 5 is a sectional view party in elevation illustrating the support for the turn-table. Fig. 6 is a plan of the bearing ring of the power apparatus. Fig. 7 is a side elevation of the same. Fig. 8 is a plan of the feed chute. Fig. 9 is an elevation of the head board. Fig. 10 is a front view of the operating lever for releasing the head board mechanism.

Referring particularly to Figs. 1, 2, and my improved press com prises an inclose rectangular box-like member 1 provided with a skeleton rectangular extension 2 as is usual in presses of this character. Slidably mounted within the inclosed portion 1 of the press is a iston 8, to which is connected a stem 4 deslgned to be operated by the power mechanism to be presently described.

The relatively upper portion or wall of the press is formed with a feed opening 5 in which is pivotally mounted a feed chute 6. The chute 6 comprises a platform 7 pivotally supported adjacent the forward edge of the opening 5, that portion of the platform in advance of the opening having flaring side walls 8, while that portion of the platform overlyin the opening being without the side wal s. Overlying the opening 5 is a guide housing 9, comprising side walls 10 and an upper or top wall 11, the latter inclining upwardly from the relatively rear edge of the opening and being provided at its relatively forward edge with a roller 12. A feeding member 13 is mounted in the feed chute 6, said member comprising an end plate 14 of a size to fit between the flaring walls of the chute and an arm connecting the plate 14 with the upper forks 15 of an operating lever 16, the platform 7 being longitudinally recessed at 17 to permit the passage therethrough of the upper forks of the lever. Below the platform 7 the lever is pivotally supported at 19 from the forward wall of the casing 1, said lever extending into the path of the stem 4 of the piston 3. The piston 3 is provided with a forward projection 19, adapted in the movement of the piston in one direction to engage the lower end of the lever 16 and move the feed member longitudinally of the feed chute, the reverse movements of the piston 4: actuating the leverin the opposite direction through the medium of a pin 20 carried by the stem and designed to engage the lever.

The relatively rear ends of the side walls of the casing 1 are formed on their inner surfaces with alined right angled slots or ways 21, the lower portion of which extends longitudinally of the casing 1, while the forward or vertical portion communicates with a slot 22 formed in the upper wall f the casing. This slot is desi ned to permit the admission of the head boards 23 for the bales, the slot being of a length and width to permit the entrance of said boards. while i within the casing 1 and form stops against which the board 23 is held in the initial operation of the press. The holding member is maintained in normal or operative position through the medium of a leaf spring 28, designed to overlie and bear upon the cross bar 25) connecting the arms.

In connection with the head boards I contemplate the use of a device for the auto matic delivery of said boards in proper position and at proper intervals in the operation of the press. This automatic apparatus includes a. bolt 30 designed to normall i overlie the slot and held in such position through the medium of a coiled spring 31. In advance of the slot 22 the upper wall of the casing 1 is provided with a standard and to the upper end of the standard is secured a spring pressed dog 33, the position of the 'dog with relation to the bolt 30 is such that when the head board is resting upon said bolt, the upper edge of said board will be engaged by the dog and retained in position to drop through the slot.

At the remote or delivery end of the press I arrange a lever 34 provided at an appro priate point on its inner surface with a projection 35, the lower end of the lever being pivoted to the press proper and the upper end connected by a wire or other flexible connector 36 with the bolt 30. As the bales with their respective head boards are fed longitudinally of the press, the head board in advance will engage the projections 35 of the lever 31- rocking the same on its pivot and withdrawing the bolt 30 from beneath the head board held between said bolt and the dog The board so held is thus free to drop through the slot 22 in position to form the head board for the next bale. ith the head board supplied as desired it is obvious that by this construction they will be continuously and automatically delivered in proper position in the press, the ways 21 guiding the boards during the formation of the bale and the stops of the holding member serving to limit movement of the boards during the pressing operation.

In connection with the press described I have devised a novel form of power apparatus by which the piston 3 may be continuously and properly operated. This apparatus, which is more particularly illustrated in Figs. 1 and t, comprises a skeleton base frame 36 on which is secured an annular member or ring, hereinafter termed the operating ring. The skeleton frame is extended beyond the base of the power apparatus to provide a housing 37 for the forward end of the piston stem 4, and connceted to the forward end of said piston and to the frame 36, preferably centrally of the latter are toggles 38. Centrally of the skeleton frame is fixed a bearing stud 39 on Which is rotatably mounted a casting 40 carrying at the upper end a plate 41 to which are secured cross arms 42. The stud 39 is preferalily of frusto-conical form, the casting, of course, being shaped to accurately fit the stud. The cross arms 4-2 are arranged at right angles, and are so disposed with relation to the operating ring 37 that in the movement of said cross arms on the pivotal support provided by the stud 39 said. arms will bear upon the upper surface of the ring. The respective ends of the toggles resting upon the upper surface of the ring 37 are arranged to be engaged by the cross arms 42. At appropriate points in the ring 37, that is at a point underlying one of the toggles when the latter is in fully open position, at 43 and at a second point underlying the other toggle when the same is in fully closed position, as at 44, the operating ring is formed with a depression which is of a size to receive the respective toggles and permit the same to fall below the upper surface of the ring, as clearly shown in Fig. 7. Secured to the cross arms 42 are sweeps 45 which project atright angles with respect to each other so that four such sweeps are arranged at equidistances apart and extending beyond the cross arms, the ends of the sweeps carrying the usual swingletrees 46 or other means for the attachment thereto of draft animals.

In the operation of the power apparatus it will be evident that in the rotation of the cross arms one of the toggles, assuming them in fully open position, will be engaged by the particular cross arm and said toggles will be forced into closed position, as will be obvious, thus moving the piston 3 toward pressing position. The closing movement of the toggles will continue until the particular toggle engaged rides into depression 44, when said toggle drops below the plane of the operating ring and, therefore, out of the path of the particular cross arm. In this position the toggles are fully closed one of them being in the depression 44 and the other disposed just beyond said depression, as shown in Fig. 4. The cross arm operating to close the toggles as described will now ride over the toggle initially engaged and engage the next toggle, thus in continued movement forcing the toggles open, such movement bein continued until the toggle now engaged ri es into its depression 43, as shown in Fig. 1, thus permitting the particular cross arm to ride overthe toggle last operated. The toggles are thus opened and closed by each cross arm, it being understood that as one cross arm frees itself or is freed from the toggle operated thereby to open the boggles, the next successive cross arm is in position to pick up the initially operated toggle to again close the toggle. The movement is thus continued durin the operation of the power apparatus, eac closing and opening of the toggles serving to insure a complete reciprocation of the stem 4 and, therefore,

pendent to operation of the pressure piston. As the stem moves forward under the 0 ening movement of the power apparatus the projection 19 engages and rocks the lever 16. This movement forces the feed member 13 longitudinally of the platform 7, such movement being continued until said member rides into engagement with the roller 12 of the housing, the further movement of said feed member tending to depress the rear or free end of the feed chute and deliver the material thereon into a position to be acted upon by the piston 3. The return movement of the parts serves to return the feed chute to normal position, again closing the opening 5 and adapting the chute for the reception of a fresh charge. The operation is thus practically automatic, the novel form of power apparatus insuring a steady and continuous operation of the pressure piston, while the movement of said piston serves to automatically feed the material at the proper time and in the proper quantity and also to provide the automatic delivery of the head boards for the bales.

Having thus described the invention what is claimed as new, is

1. A baling press formed with a feed opening, a feed chute normally closing said. opening, and means operated in the movement of the plunger to actuate the feed chute to uncover the opening and simultaneously deliver the material from said chute through the opening.

2. A baling press formed with a feed opening, a feed chute normally closing said opening, a feed member mounted in the chute, means actuated by the piston for operating said feed member, and means carried by the press for causing the feed member in operation to tilt the feed chute into delivery position.

8. The combination with a baling press and a piston therefor, of a power apparatus for said piston including a plurality of indegles connected to the piston, an operating ring for supporting said toggles, said ring being formed with depressions to receive the toggles, and means for engaging said toggles in succession and operating them respectively in opposite directions.

4. The combination with a baling press and a piston therefor, of a power apparatus for said piston including a plurality of independent toggles connected to the piston, an operating ring with which said toggles are arranged in contact, said ring being formed with a plurality of depressions corresponding respectively with the closed position of one toggle and the open position of the other, and cross bars adapted in operation to successively engage the respective toggles and force them into registry with the ring depressions.

5. A baling press formed with a feed opening, a feed chute normally closing said opening, and means operative in the feeding of the material for actuating the feed chute to uncover the opening.
